Byoung-Soo cho. Department of Pediatrics, College of Medicine, Kyung Hee University, Seoul, Korea. Effect of Siryungtang, Steroid, Interferon-γand Cyclosporin-A on Mitogen Interleukin4-Activity in Minimal Change Nephrotic Syndrome. Proceedings of International Symposium on East-West Medicine, Seoul. 183-186, 1999. -We have reported that patients with childhood minimal change nephrotic syndrome (MCNS) express higher levels of IL-4 mRNA expression by mitogen activated T cells using Northern blot(Cho,et al, JASN 1:518,2:590). Siryungtang(SA-1) is an oriental medicine shich has long been used in chronic renal diseases. In order to evaluate the efficacy of SA-1 on IL-4 sctivity from the monouclear cells isolated from the MCNS patients(n=5) and controls(n=5). Cells were adjusted to 2×107cells/ml with 10% FCS-RPMI and added test drugs such as SA-1, steroid(hydrocortisone, HC), CsA, IL-4& combination of SA-1+HC,SA-1+CsA&SA-1+IFN-γand mitogens(PHA-P:20㎕/ml, Con-A:20㎕/ml & PMA:50ng/ml) were added. Cells were cultured at 37℃,5% CO2 incubator for 24,48 & 72hrs. Results were as follows. 표 Mean ³[H]thymidine incorporation(cpm) was higher in controls(44,920±7,482cpm)that in patients with MCNS(30,495±2.135). However ³[H]thymidine incorporation was reduced by adding SA-1,HC, CsA & IFN-γ,or which CsA was the most effective, by combination treatment with SA-1 to steroid and CsA, significant additive effects were noted in MCNS group. In conclusion SA-1 has a steroid and CsA sparing effect and could reduce side effects of steroid and Cas significantly if clinically applicated.

Soo‑Bae Kim,Jae‑Gil Jung,Young‑Hee Cho,Su‑Hyeon Kim,Kwangjun Euh,Jung‑Moo Lee 대한금속·재료학회 2022 METALS AND MATERIALS International Vol.28 No.7

The effect of ultrasonic melt treatment (UST) on the solidification microstructure of an Al–5Ti–1B alloy containing highvolumefractions of Al3Tiand TiB2particles is investigated for various UST times with different melt holding times. Theas-cast Al–5Ti–1B alloy is composed of TiB2and polygonal Al3Tiparticles (present prior to UST), plate-like Al3Tiparticles,and Al grains (formed during UST and/or solidification). The UST causes a size reduction and homogeneous distributionof the TiB2-agglomerated region containing many submicron-sized TiB2particles pushed to the grain boundaries. The USTslightly decreases the size and improves the distribution of polygonal Al3Tiparticles enriched in the TiB2-agglomeratedregion. Unlike the TiB2and polygonal Al3Tiparticles, which exhibit a minor refining effect, the plate-like Al3Tiparticlesshow a significant refinement with UST application. The UST has a significant effect on the size distribution of Al grains byinducing the formation of medium-sized grains at the expense of small and large grains; however, it only has a slight effecton grain refinement. The degree of microstructure modification increases with increasing UST time but decreases with meltholding time after UST. The mechanisms for the refinement and dispersion of the TiB2and Al3Tiparticles and Al grains arediscussed considering fragmentation, nucleation, and growth behaviors induced by the UST and subsequent solidification.

Background: The present study was performed in order to identify the possible future location of the Department of Emergency Medicine and future demand for and supply of manpower through a survey of the heads of Kwangju City and Chollanam-do hospitals. The survey covered the degrees of recognition and understanding, the necessity, the future prospects, and the direction of development of the Department of Emergency Medicine. Methods: A total of 33 large-scale general hospitals were selected in county districts having more than 200 sickbeds as of November 1999. Among them, the heads of 29 hospitals responded to the survey. The survey had a total of 31 questions, including 6 questions on the status of the emergency room. Six(6) questions concerned the degree of recognition of the Department of Emergency Medicine. Six(6) questions concerned the degree of understanding of the Department of Emergency Medicine. Six(6) questions concerned the necessity for the Department of Emergency Medicine, and 7 questions concerned the future prospects and direction of development. The results of the survey were analyzed. Results: 1) As to the question of the degree of recognition, the Department of Emergency Medicine was known to all. That is, 50% of the respondents were well aware of the department, and 50% a little, Nineteen(19) respondents(65%) answered that it was convenient to have the Department of Emergency Medicine in a university hospital, among which 16 respondents(55%) answered that it was because of the rapid treatment of emergency patients. 2) As to the question of the degree of understanding, particularly, the areas of medical examination and treatment by the Department of Emergency Medicine, 15 respondents answered that it was for the treatment of patients who needed to receive emergency treatment, while 12 respondents answered that it was for the diagnosis and treatment of all patients who visited the emergency room. Only 7 respondents(24%) answered positively as to the possibility of the Department of Emergency Medicine using thrombolysis medicine. 3) All except for one respondent had a positive view on the necessity for the Department of Emergency Medicine, and all except for 3 respondents wanted to have specialized doctors in emergency medicine work at the corresponding hospital. As to the type of schedule, 10 hospitals(34%) wanted to have only night shifts, and 11 hospitals(38%) wanted to have both day and night shifts. Most hospitals needed two or more workers in the field. 4) As to the question of the direction of development, many respondents were of the opinion that the hiring of specialized doctors in emergency medicine would not be of greatly help to the finances of the hospital due to increased labor costs. It seems that improvement of the medical system to improve hospital financing is a required prerequisite for the development of the Department of Emergency Medicine. Also, 21 respondents(83%) were of the opinion that it would take a considerable amount of time to activate the Department of Emergency Medicine with respect to the future prospects of the department. Conclusion: It was shown in the present survey that the heads of hospitals in Kwangju City and Chollanam-do recognized the Department of Emergency Medicine in a positive way, but it was necessary to establish both a delivery system for emergency medicine and collaboration with and support by other medical areas for its future development. It was estimated that in the future, more than 55 doctors specializing in emergency medicine would be needed as medical manpower for the general hospitals in the districts.

Objectives : The aim of this study was to examine the behavioral and emotional problems associated with nocturnal enuresis in Korean children. Methods : Three hundred eighteen children with nocturnal enuresis, together with their parents, completed the Child Behavior Checklist (CBCL), Disruptive Behavior Disorder Scale according to DSM-IV (DBDS), Children's Depression Inventory (CDI), State-Trait Anxiety Inventory for Children (STAIC), and Piers-Harris Children's Self-Concept Scale (PHCSC). Ninety-three normal students were selected as the control group. Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in the nocturnal enuresis group according to the CBCL results. The nocturnal enuresis group also scored significantly higher in the ADHD and ODD profiles of the DBDS. The nocturnal enuresis group was more depressed and anxious than the control group according to the results of the CDI and STAI. The mean score of the PHCSC was significantly lower in the nocturnal enuresis group when compared to the normal control group. Conclusion : The results of this study suggest that children with nocturnal enuresis in Korea have clinically relevant behavioral and emotional problems. The findings support the link between nocturnal enuresis and psychopathology in Korean children.
